Replication of DNA begins at a single origin of replication and then proceeds the entire length of the strand, in one direction (T/F) - correct answer False What enzyme is responsible for relieving the stress associated with the twisting and untwisting of a DNA strand during replication. - correct answer Topoisomerase As a replicated DNA strand elongates, what enzyme is responsible for adding nucleotides? - correct answer ...

DNA - ANSWER-Double stranded polynucleotide formed from two separate chains of covalently linked deoxyribonucleic units. It serves as the cell's store of genetic information that is transmitted from generation to generation. Double Helix - ANSWER-The typical structure of a DNA molecule in which the two complementary polynucleotide strands are wound around each other with base pairing between the strands. Base Pair - ANSWER-Two complementary nucleotides in an RNA or DNA molecule that are h...

Which of the following correctly describes the shapes of the major and minor grooves in double-helical RNA? The major groove is narrow and deep - ANSWER - The major groove is narrow and deep and the minor groove is wide and shallow. The underlying principle of "classical" methods of DNA sequencing is to separate, by size, nested sets of DNA molecules. There are two main steps involved: (1) running a PCR-like sequencing reaction and then (2) running the extension products through a gel matr...

Enzymes Involved in DNA Replication Final Prep-Exam Test 2024. Helicase - ANSWER Uses the hydrolysis of ATP to "unzip" or unwind the DNA helix at the replication fork to allow the resulting single strands to be copied. Primase - ANSWER Polymerises nucleotide triphosphates in a 5' to 3' direction. The enzyme synthesises RNA primers to act as a template for future Okazaki fragments to build on to. DNA Polymerase III - ANSWER In charge of synthesizing nucleotides onto the leading end i...
